| 581013 | 2007-08-15 03:03:00 | Thanks for the comments guys. I'm reluctant to make it tap off another power source, for the pure reason that plugged into the motherboard it will kick into high-speed mode when the case temperature reaches a certain level. Hence why I figured that simply reducing the current going to it inline will still allow for it to go into a faster speed mode when it needs to. | somebody (208) | ||
| 581014 | 2007-08-15 04:07:00 | There's nothing stopping you using the fan header, although it won't reach the speed it does now even at the hottest temp. | Murray P (44) | ||
| 581015 | 2007-08-15 06:36:00 | Why not just replace it? Glacialtech case fans are pretty nice |

| 581016 | 2007-08-15 09:32:00 | I could replace it, but given that I spent more on this PC than I had originally hoped to, I don't want to buy anything else for it. | somebody (208) | ||
| 581017 | 2007-08-15 09:59:00 | I have a case fan in a PC I want to slow down... Does anyone know whether this will work, and if so, what size resistor do I need to go for? Try a 47ohm half watt fixed resistor. I have a small100 ohm pot on the power supply fan, which gives a good range of control |

| 581019 | 2007-08-15 10:19:00 | Try a 47ohm half watt fixed resistor. I have a small100 ohm pot on the power supply fan, which gives a good range of control I agree. I bought a 12cm case fan last week that sounded like a 747 taking off. Wiring a 33ohm resistor in series with the 12V line dropped the RPM from 2200 to 1450, cutting the noise right down while still providing enough cooling. |

| 581020 | 2007-08-15 10:48:00 | Get a 50 ohm variable res from tricky dicks works fine for me from stop to full speed just mount in the side panel get a knob as well all up about $5 | drys (347) | ||
| 581021 | 2007-08-15 20:48:00 | Thanks all. I squirted a bit of silicon lubricant into the fan a couple of days ago and it seems to have quietened down a fair bit. I'll keep this in mind if the noise level starts picking up again. | somebody (208) | ||
